윈도우 머신이 꼭 필요한 이유중에 하나가(Mac은 비싸서 안되고) Lightroom이고 간혹 비디오 편집을 하려고 하면 Sony Vegas가 참 간단하고 좋은데, Lightroom 대체할 만한것은 아직 없다고 보여지고요. 비디오 편집은 요구사항이 많지 않아서 어디 있을것 같아서 찾아봤는데...

리눅스에서 비디오 편집하는것이 아주 나쁘지는 않네요. kdenlive라는 툴이 KDE env인데, 괜찮은것 같네요. 버전도 높고요. GNome도 곧 V1.0으로 발표하는듯. 그런데 NVidia 카드가 있어서 GPU Agpu acceleration(하드웨어 가속기)를 enable하려고 하니 역시 리눅스는 복잡해...

FFMpeg을 다시 컴파일하면 되는데, NVidia 얘네들은 리눅스 지원이 진짜 지랄같애서(요즘 많이 좋아졌다는데) 하다가 욕나오는데... shotcut이라는 얘가 이미 다 포함시켜 놨네요.

I had to manually mount the CD: sudo mount /dev/cdrom /media/cdrom

Install the necessary packages: sudo apt-get install make gcc linux-headers-$(uname -r)

Install the Guest Additions: sudo /media/cdrom/VBoxLinuxAdditions.run

Now you can mount your share using:

mkdir ~/host

sudo mount -t vboxsf La_Build ~/host

윈도우 command line이 좀 dull하니까 이것을 리눅스의 bash 처럼하려는 시도인것 같습니다. cygwin도 좋은데 이것도 좋은 시도네요.

--------------

Overview

Clink combines the native Windows shell cmd.exe with the powerful command line editing features of the GNU Readline library, which provides rich completion, history, and line-editing capabilities. Readline is best known for its use in the well-known Unix shell Bash, the standard shell for Mac OS X and many Linux distributions.

Features

• The same line editing as Bash (from GNU’s Readline library).
• History persistence between sessions.
• Context sensitive completion;
  • Executables (and aliases).
  • Directory commands.
  • Environment variables
  • Thirdparty tools; Git, Mercurial, SVN, Go, and P4.
• New keyboard shortcuts;
  • Paste from clipboard (Ctrl-V).
  • Incremental history search (Ctrl-R/Ctrl-S).
  • Powerful completion (TAB).
  • Undo (Ctrl-Z).
  • Automatic “cd ..” (Ctrl-Alt-U).
  • Environment variable expansion (Ctrl-Alt-E).
  • (press Alt-H for many more…)
• Scriptable completion with Lua.
• Coloured and scriptable prompt.
• Auto-answering of the “Terminate batch job?” prompt.

Usage

There are a variety of ways to start Clink;

1. If you installed the autorun option then simply start cmd.exe. Run clink autorun –help for more info.
2. To manually start, run the Clink shortcut from the Start menu (or the clink.bat located in the install directory).
3. To establish Clink to an existing cmd.exe process, use “<install_dir>\clink.exe inject”

ARM에 맞는 stable kernel을 관리해주는 사람이 있었네요. 중요한 feature는 back port도 해주고 아주 친절하네요.

Linaro Stable Kernel (LSK)

Overview

Linaro Stable Kernel (LSK) aims to provide a stable basis for system integration of ARM hardware, integrating Linaro developed features available in mainline with kernel.org Long Term Stable (LTS) releases to allow integration of those features in production systems.

Most LSK features can be disabled at either build or run time so are included as part of the core LSK functionality. To support those feature sets which have substantial impacts on the kernel and cannot be disabled at build or run time the LSK is provided in multiple flavours. Currently these are:

• "Core" - features which can be runtime disabled

• "Android" - additional changes from AOSP

• "RT" - the RT patch set adding realtime features to the Linux kernel

The number of flavours is kept to a minimum in order to make selection simpler. As much as possible is in the core LSK in order to ensure that features are as widely available as possible.

Currently the LSK release in Feature mode is base based on kernel version v3.18. Note: details for maintenance mode LSK versions can be found below.

Support

Each Linaro Stable Kernel (LSK) is maintained for two years. During the first year [Feature-Mode], both features and bug fixes are integrated and during the second year [Maintenance-Mode] only bug fixes are integrated. Bug reports should be filed against Linaro Stable Kernel project. Any queries should be directed to the Linaro support system in the first instance.

Adding code to LSK

Any bug fixes which apply to the standard kernel and could be included in a kernel.org LTS release should be submitted there, the kernel.org LTS releases are integrated into the LSK.

New features need to be reviewed by the TSC in discussion with the LSK team. Features should be present in current versions of the upstream kernel or in the process of being integrated there.

Code specific to the LSK should be submitted to the LSK team for review by e-mail using standard kernel submission techniques such as patches in e-mail or git pull requests. The addresses to send things to are:

• LSK Tech Lead: Kevin Hilman <khilman AT linaro DOT org>

• LSK Engineer: Alex Shi <Alex.Shi AT linaro DOT org>

• Linaro Kernel mailing list <linaro-kernel AT lists DOT linaro DOT org>

Please include "LSK feature request" in the Subject line.

The submission should include information to help track upstream work on the feature, in order of preference:

1. Commit IDs from the standard kernel in the changelogs of the individual patches.
2. A description of how the equivalent change was made upstream or why it isn't required in LSK (eg, explaining that this is taken care of by features not present in the stable kernel).
3. References to where out of tree development is happening including contact information for followup.

This will aid ongoing maintenance of the features. Any new features should be discussed with the LSK team in advance to determine the most straightforward approach.

Features in LSK v3.18 [Feature Mode]

Getting LSK

Linaro Stable Kernel (LSK) is available in a git repository on git.linaro.org. There are branches for each flavor of the kernel:
